Issue with Live Streaming #41

Open stakach opened 9 years ago

stakach commented 9 years ago

The player seems to be having trouble playing dash streams formatted like:

<?xml version="1.0" encoding="UTF-8"?>
<MPD xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:mpeg:dash:schema:mpd:2011" xsi:schemaLocation="urn:mpeg:dash:schema:mpd:2011 http://standards.iso.org/ittf/PubliclyAvailableStandards/MPEG-DASH_schema_files/DASH-MPD.xsd" type="dynamic" minimumUpdatePeriod="PT2S" availabilityStartTime="2015-08-19T03:33:52" minBufferTime="PT4S" suggestedPresentationDelay="PT20S" timeShiftBufferDepth="PT1M0S" profiles="urn:mpeg:dash:profile:isoff-live:2011">

      </Representation>
    </AdaptationSet>
  </Period>
</MPD>

The console produces the following errors at try.js:56:

Loading manifest, url='http://sohiptvlb2.soh.com/sdtv/ch09.mpd'

Couldn't find media presentation duration

The DASH standard seems to support a lot of different representations
